Each New Year promises an exciting year ahead, and conservation science is no exception! As biologists gear up for the field season, CWF’s amphibian programs are particularly noteworthy.

Our Amphibian Crossing Project has made major strides in protecting the frogs, toads, and salamanders migrating to breeding areas, and we’re launching a new program this year to better document the newly discovered mid-Atlantic coast leopard frog. You can help CWF biologists collect data and save these fragile creatures.

Read below for more details about each program. In the meantime, if you would like to support CWF’s amphibian programs, please visit our YouCaring page here: https://www.youcaring.com/conservewildlifefoundationofnewjersey-1091698 . Your contribution will help us develop training materials and cover research expenses to protect our most vulnerable frogs and salamanders!

Amphibian Crossing: A New Twist on an Old Program

The long-standing Amphibian Crossing Project, established in partnership with the New Jersey Endangered and Nongame Species Program (ENSP) in 2002, has been organizing dedicated volunteers each spring to chauffer migrating amphibians across roads as they trek from their upland hibernation sites to their breeding ponds. This program has saved thousands of frogs, toads, and salamanders from vehicle strikes so that local amphibian population sizes can be maintained, which is especially important for species of concern, such as the Jefferson and spotted salamanders.

Seeking a more long-term solution to the amphibian road mortality problem at the Amphibian Crossing Project’s top site, ENSP has finally secured funding to construct crossing structure system for amphibians to move safely across Waterloo Road in Byram Township, Sussex County. This system, including under-road tunnels and guide fencing, will help amphibians avoid problems on the road all season long. CWF is preparing its second year of monitoring along Waterloo Road to track the changes in amphibian vehicle-caused mortality before and after this system is installed.

Leopard Frogs: A New Program for a New Species

This year marks the launch of CWF’s Kauffeld’s Calling Frogs program. Similar to New Jersey’s Calling Amphibian Monitoring Program (CAMP), volunteers will listen and document frog calls during the breeding season. Kauffeld’s Calling Frogs, however, will focus specifically on the newly discovered mid-Atlantic coast leopard frog. This frog, named after the late avid herpetologist Carl Kauffeld, had been mistaken as a member of the southern leopard frog species for decades. Only recently was it determined to be a separate species with unique habitat requirements.

Despite only being an official species since 2014, it is already considered a Species of Greatest Conservation Need in New York, and may be declining from other portions of its range. CWF biologists are eager to document the current extent of this frog’s range within New Jersey in order to monitor the population for possible declines. Knowing where this species is found is the foundation for future research into its habitat needs and threats.

Getting the Public Involved

These amphibian programs cannot move forward without the dedication of CWF volunteers. Over 100 volunteers have been involved with the Amphibian Crossing Project, and a dozen more dedicated at least a day a week for months to monitor Waterloo Road amphibian mortality. With the success of CAMP in mind, this first year of Kauffeld’s Calling Frogs promises to be full of new frog population discoveries.

Just in time for next week’s Great Backyard Bird Count, The (Bergen) Record’s Jim Wright takes a look at the hairy woodpecker with help from CWF Executive Director David Wheeler. This backyard birdwatching favorite is still a common sight on many New Jersey feeders and tree trunks, but remains vulnerable nationally due to its nesting reliance on old tree snags.

Statewide Census Documents over 650 nesting pairs in New Jersey

by Ben Wurst, Habitat Program Manager

An osprey prepares to land on a natural nest. Barnegat Bay, NJ.

Since we began to work more closely with ospreys in 2006, we have documented the population grow beyond the historic population estimate of 350-450 nesting pairs (Henny 1977) to a new historic milestone. In 2017, a total of 668 active nests were recorded during a statewide census of nesting ospreys, which is well above the post-DDT milestone of 500 nesting pairs, and show that the population continues to grow. This is the second census conducted without the use of manned aircraft since 2009 after all known osprey nests were released and mapped online in 2013. Despite the lack of aircraft, we’re still able to obtain an accurate representation of the size and health of the statewide population, while reducing the overall project cost. (more…)

On a Tuesday morning, Conserve Wildlife Foundation of New Jersey biologist Allegra Mitchell and I, GIS Intern Taylor Forster, went to the New Jersey State Museum in Trenton. We were looking at a newly identified species recently found in one of the largest metropolitan areas – New York! I learned that this species was discovered because of its unique “call.” A “call” is the sound a male frog makes to attract a female frog, and each frog species’ call is unique. It seems that this species remained undiscovered for so long because of its similar appearance to other, closely-related leopard frog species. The cryptic nature of this new species meant that the only noticeable distinction between it and other leopard frogs was the sound it makes.

After looking at this newly discovered frog, now known as the mid-Atlantic coast leopard frog, a few defining characteristics came to light that set it apart from the other leopard frogs. These characteristics make it easier to identify other mid-Atlantic coast leopard frogs that have been preserved and categorized as other species for museum collections. With this information in mind, Ms. Mitchell and I were at the New Jersey State Museum to investigate when and where this frog had been found throughout the state before anyone realized its significance.(more…)
